Final answer:
In a peds trigger finger surgery, the flexor tendon sheath should be released along with the A1 pulley to improve finger movement and alleviate constriction.
Step-by-step explanation:
In a peds trigger finger surgery, along with the A1 pulley, the flexor tendon sheath should be released. The flexor tendon sheath is a protective covering that surrounds the flexor tendons in the fingers. When the A1 pulley becomes thickened or constricting, it can cause triggering or difficulty in finger movement. Releasing the A1 pulley along with the flexor tendon sheath helps to alleviate the constriction and improve finger movement.
